Transulnar Versus Transradial Access for Coronary Angiography and Percutaneous Coronary Intervention: A Meta-Analysis of Randomized Controlled Trials

•Transradial approach is the preferred access-site for coronary angiography and interventions, but has limitations.•Transulnar approach is an alternative forearm access-site for those who fail or are not candidates for transradial approach.•Comparative data on the outcomes of both approaches are limited. This meta-analysis demonstrates similar safety and efficacy.
